Computational analysis and modelling of wave propagation and interaction with objects are essential to help understand the fundamental problems of wave travelling. Though various methods have been proposed to model the wave propagation procedures, Monte Carlo simulation plays important role as an effective method to trace individual phone history, based on the statistics of large photon populat...

The performance of wireless communication systems depends on the radio wave transmission path between the transmitter and the receiver. Unlike wired channels that are stationary and predictable, radio channels are extremely random. In addition, electromagnetic wave propagation characteristics vary significantly over different frequency bands. Therefore it is vital to thoroughly understand the p...

An analysis is presented for transient response of a mode-III interfacial crack propagating between two dissimilar piezoelectric half spaces. The dynamic fracture toughness of a piezoelectric interface is examined, which is a central issue related to the interface strength of multi-layered sensors and ferroelectric thin film devices. For the mode-III crack propagation in piezoelectric materials...

Laboratory ultrasonics provides an ideal opportunity for studying wave propagation in random media. Models are relatively easy to construct and both the phase and amplitude of the wave field can be measured, so we can separate the coherent from the incoherent intensity. Here we show detailed measurements of wave propagation in a 1D strongly scattering medium that fit the theory of radiative tra...

To implementation of mobile ad hoc network wave propagation models are necessary to determine propagation characteristic through a medium. Wireless mobile ad hoc networks are self creating and self organizing entity. Propagation study provides an estimation of signal characteristics. Accurate prediction of radio propagation behaviour for MANET is becoming a difficult task. This paper presents i...

Transient wave forms in neural networks with diffusive and nonlocal coupling have attracted particular interest because they may mediate recruitment of healthy cortical tissue into a pathological state during migraine. To investigate this process, we use a reaction-diffusion system of inhibitor-activator type as a generic model of pathological wave propagation and set it close to bifurcation in...

This paper presents results of measurements campaign carried out at a carrier frequency of 24GHz with the help of TPLINK router in indoor line-of-sight (LOS) scenarios. Firstly, the radio wave propagation strategies are analyzed in some rooms with router of point to point Ad hoc network. Then floor attenuation is defined for 3 floors in experimental region. The free space model and dual slope m...

In this paper, we introduce developed technologies for millimeter-wave inter-vehicle communication (IVC) system in intelligent transport systems (ITS), especially propagation characteristics of 60 GHz band for the system design of IVC. First we introduce the outline of an IVC system using millimeter wave and its research subjects. Next we show experimental results of propagation characteristics...
